Hello everyone,
I'm having isssues with mobile data on my N4 after I replaced my digitizer and lcd screen. I dont have problems with WiFi, I also can call others, and others can call me, same with SMS's, but I can't access the internet. As I disconnect my WiFi, signal bars turn orange or get exclamation mark(tried on both kk and lollipop). It shouldn't be an issue witg the antennas, because SMS and calls work(wich also use cellular). Could be wrong though.
I'm also having weak singnal. In my area there is usually sufficient coverage, but in the moment I one bar indoors, 1 or 2 bars near windows(enough for calling, but too little for mobile data), but I used to have 3-4 bars indoors. Any fix to that?
Any help is welcome.
Edit: got access to internet by readjusting APN(duh). Never thought of that beause it usually does it itself.
Are you sure APN settings are correct ? I'm using TELE2 (Lithuania) and default apn settings are wrong - I need delete proxy server and proxy port from apn to have working mobile data ...

Yeah, I thought about that right after posting, and I got that fixed already,(I have also TELE2) but I still have reception issues. Anyway, thanks for participating.
for weak signal first what I would check - coaxial cable from mainboard to gsm antenna (plastic part above usb port) and maybe antenna connection pads.
have you tried 2G mode ?

The cable seemed fine to me, and the pads were okay. It might be just me, but it feels that the reception is getting better. I'm having almost constant 2G now indoors(before I almost had none).In 2G mode almost nothing changes, exept that it doesn't get occasional momentary 3G, like it does in 3G preferred mode.
I was wrong about the reception. Now it comes and goes absolutely random.

Problem solved. During the digitizer replacement I removed the electrostatic discharge tape. Replaced that with the insulating tape and now works fine.

Hi,
I've same issue, everything else are working fine but I get very low signal or no service at all. Where is this tape located?

It would be REALLY helpful if after you solved it, you could tell us the exact location, so any other person out of 7 billion people on earth, could solve it, including me.

First, I only thought at the time that it was solved, however I was wrong. I have reception only near cities.
Second, I put the tape over the coaxial cable and covering some of the battery as well.

My wifi has been working great up until today. For some reason it's really weak. The only way I can get a signal is to literally put my phone inches away from my router. It won't see any hotspot more than a feet away. Anyone know what's wrong?

There's a setting for the wifi power, I would check that first to see if it's gotten moved:
settings -> all settings -> connections -> wifi -> Advanced -> Power Mode Tab
"Best Battery" end of the slider uses the least power, but can make it darn near impossible to get or maintain a connection.
I've got the same problem, and did the Best Performance, but no change. Any one has a clue?
same thing here. My school has wifi everywhere and when im in class i get like 1 bar of connection compared to everyone else who gets way better connection then i do
seems like everyone is having this problem recently. i had it and had to send it it to HTC, from what i understand its because the bluetooth/wifi antenna is loose. some guy in another thread opened his up and pushed down the antenna connections and was fine.

yea im not comfortable with opening this phone up.
not worth it
at home its fine but at school it sucks
oh well
This is my only gripe with the new ROM.
WIFI is TERRIBLE!
As for the Coax being loose, I would consider that an anomoly.
I had perfect WIFI access before the new ROM and I kind of doubt flashing to a new ROM zapped my cables out of place!

Connector do come loose. My wifi was fine and I started to have very low stength. Did everything but nothing worked. See my ordeals:
http://forum.xda-developers.com/showthread.php?t=828036
Finally opened up the unit and snapped connectors to their places. It is fine now. See my post #4 in the above thread.
Yes, you will void your warranty, so do this at your own risk.
Hi,
Ok, so I dont have a network signal now.
This started to happen when I dropped my nexus 4.
It was ok until I dropped the phone. I suspected that it really was a hardware problem, the software seems to get signal.
Here are the screen shots I took when I dial *#*#4636#*#*.
I tried changing wcdma preffered to wcdma only and back again to wcdma preffered again, nada.
See, there is a signal. I suspected the sim card so I bought another one. But still, no joy.
I also went back to all stock (latest), coming from cm10.1. I formated everything, but I still get the "emergency calls only".
This really bugs me out. I can access the sim card (contacts in it, sim services, it all works). I also get signal levels like other phones outside of a building (around -54dBm).
So why, just why wouldn't it work? please give me ideas.. My last hope is to take it to an lg store, but since I am in a different country where I bought it, I guess I won't be able to get any warranty (it was bought by my brother).

If u didn't have access to the sim card I would say that it may have moved, but if u do I am sure it is a hardware problem. If the phone doesn't have dropping singals u could not have any charge by sending it to the SAT.
Good luck!

That's the very reason I'm baffled. the phone is perfectly fine except for the signal. If it's hardware, then shouldn't I get a waaayy lower signal levels?
AND!!!!! I can freaking search for available networks, I CAN DETECT THEM. That really freaks me out.
If it really is the hardware, what is it? I recon the radio/antenna is fine since i can detect signals and networks, I also believe that the radio controllers are integrated to the processor SOIC. Sheeesssshhhhh..... I'm enticed to prop the thing open, maybe some just loose ribbon connection or.. sumthin..

There may be damage in some parts of the antenna and not in all of it. Take it to the sat asap if it doesnt have signals of the drop

Do you still have the problem? Because, I have the same issue on my Nexus 4 since 4.3. Sometimes it loose GSM carrier, sometimes it ask (again) the PIN code.

Yes.
I tried reseating/cleaning the SIM and am waiting to see if that helps. Some have seen success by using tape to stop the SIM touching the edge of the SIM carrier. Odd that that should work if the problem is caused by poor GSM coverage...

Maybe the problem was there in 4.2.2 but was not visible. I just have put some tape on the GSM coverage to isolate the ship pins, and hope that it will solve it. First good point, the phone still works with the tape inside! It seems also that the GSM signal level is better
Wait & See...

Hope you can SIM out again
A SIM is a digital device to which the phone communicates using a protocol. It should either work or not work. If the connection to it bad I would expect it to work intermittently and be sensitive to physical knocks or the phone's physical position. I don't see how it would affect signal strength.

Signal strength hasn't changed, only the phone position inside the "Faraday bunker" where I work!
Thank you!

HI. I had this WiFi problem since I bought the phone like 6-7 months ago.
My previous phone was a Nexus 4. It had good wifi reception. From my apartment I could find like 6-7 routers with +2 signal bars.
My Lg G2 sees only 3 routers, mine and 2 others that are at 1 signal bar or sometimes no signal. I tried to flash other basebands but no improvment. I tried flashing other ROMs.
I now tried to lift the little conectors on the back cover and put a little piece of paper under so i'm sure they connect (i don't know if that's how wifi works because it's working the same with or without the back cover).
What else should I try? Is there something to do or every G2 has signal problems?
I might have a solution for you...

I had a similar problem with my G2. The old phone (Optimus 3D) had good and strong wifi signal. With this one, from the first day to connect to home network, I had connection problems and all I had to do was to set to one network mode (and only one - I use G), on a single channel (give it a low one - 1 to 6) and a 20 Mhz band channel. And guess what: I can have a clear and strong enough (plus stable) from down the street, while my flat is at the third floor.
Please try to modify your modem/router settings as stated before and let me know the results.

My router works fine. I have it on G/N 20Mhz Channel 5. I work installing internet antennas on top of buildings so I would like to access the routers from far away.
Another question. What's the purpose of the gold connectors on the back cover?I have like 3-4 pairs. My wifi, network and gps work with or without the cover. No difference.

You must have only one type of connection. Or at least in my case is so. I have only G, not mixed one. As for back cover connectors...I have none. Stock back cover, gold edition of D802.

My brother sees 8 wifi routers with 3+ signal bars with an old Sony xperia tipo. I see only 3
I was wondering if anyone here is familiar with the Note 4 antenna hardware... Recently my Note 4 fails to connect to 3g / LTE networks though it connects and works absolutely fine with basic 2g networks. I ruled out everything I could software wise and also ruled out a sim card error leaving just a hardware fault to blame...
By chance this morning I just happened to be about 700m away from a cell phone mast so re-enabled 3g / LTE in network mode and to my amazement it connected to 4g and 3g with full signal strength and worked fine. Testing it again just 1.5km away resulted in the same issue... no 3g or LTE just 2g. This all leads me to believe that this is likely an antenna issue?
I replaced the motherboard in this phone (EMMC error) a long time ago and the charging / mic / button block at the same time as it could be a bit unreliable... the phone has been faultless since (until this much more recent issue with signal).
I know my way around the inside of the phone reasonably well but I can't seem to find out whether the antenna is purely made up of just the charging block, the blue & white wires connecting this block to the motherboard or a combination of both?... does anyone know the answer to this?
Both wire connectors and charging blocks are fairly easy and cheap to source and replace so doing both seems to be the route I'm heading down at the moment but I'm curious if it could possibly be only one part that is at fault (given that the antenna must be working to some extent to connect to 2g networks) ?
Anyone have any ideas?

Thanks for your reply the parts are in order but won't be here for a few more days yet... I'll let you know the outcome...
Just to conclude this thread I first replaced the antenna wires then later the antenna / charging port block neither solved the issue and so it would seem it's a fault with hardware on the motherboard. Probably an isolated case as I've yet to come across another mention of such an issue.

I just started having this issue after the first of January. I was told it was because the 3G was disconnected by the cell provider and that the Note 4 defaults to the 3G antenna. So my question is if anyone knows if there are two antennas in the Note 4 and if one is specifically for 4G? Or if there is a software update that can resolve the issue?
